GOMBINED'WATER HEATER A1331 STEBILZZING ASPPARATUS.

Application filed December 8, 1924. Serial No. 754,818.

This invention relates 'to a combined water heater and sterilizingapparatus adapted to be used more particularly by barbers, dentists, andother users requiring frequent supplies of relatively small quantitiesof hot water and steam for shaving, laving, moisteningand sterilizingpurposes.

The main object is to provide a compact and easily portable containerwith intercommunicating chambers, one of which is adapted to receivethe-water to be heated and contains an electrically heated element forimparting the necessary heat to the water therein while the othercontains means for supporting articles to be moistened or sterilized bythe heated water or steam from the receiving chamber.

Another object is to provide the sterilizing chamber with a perforatedplate or tray, adapted to receive and support the articles sterilizedabove the normal level of the water which may be transferred to thesterilizing chamber from the water adhering to or thus permitting theexcess held in saturation by, said articles to drain into the underlyingportion of the sterilizing chamber.

Other objects and uses relating to the specific parts of the apparatusWill be brought out in the following description. In the .drawings:'

. Figure'l is a vertical sectional view of an apparatus embodying thefeatures of my invention. j

As illustrated, this apparatus comprises an uprightcontainer 1',consisting of ,cylindrical shells, 2 ant 3, one of which as isofrelatively large diau'reter to form what maybetermed a sterilizingchamber L, the. other chamber -2-' beheating chamber,

' ing of greater vertical length than the shell to extend some distancebelow and 'above the bottom and top' thereof and forms what may be;termed .a water receiving cham- The shell 3-v is provided in one sidewith a lengthwise recess 16 of substantially'circular cross sectioncorresponding to the diameter ofthe shell 2 which it is barbers,dentists or others who may find use In other ords the portion of theshell 2- which is embraced by the adjacent portion of the shell 3-constitutes a partition wall 7 which is perforated to establishintercommunicating passages between the chambers land 5- and between thebottom wall as S and the top wall as 9 of the chamber 8-.

The bottom 2 of the shell -2 is provided with an inlet -10 adaptedto beconnected by a pipe -l1- to any available source of water supplyfrom-Which water may be fed into the chamber 5 where it is adapted to beheated in a manner presently described.

The upper end or top -12 of the shell -2- is secured in place by screws-13 and serves as a part of the support for an electric heater 14;.

This heater is similar to that set forth in my pending applicationSerial Number 751,065, filed November 20, 1924 and is also suspendedfrom the top 12 in a similar manner to be partly or completely immersedin the water in the chamber 5.-

Electric current may be supplied to the heater 1 l from any availablesource and inay be controlled by the temperature of the water in thechamber '5 through the medium of an electric switch l5 and athermostatic bar l6 constructed and arranged in a manner similar to thatset forth in my pending application above referred to except that theouter jacket for the shell 2 is omitted.

The bottom -8- of the sterilizing chamber l is disposed in a horizontalplane some distance above the bottom 9-" and also some distance belowthe top ,12- of the shell -2- and is provided with an outlet pipe 17leading to afaucet 18 from which the hot watermay be drawn in smallquantities as needed.

As previously explained the partition 7* between the chambers l and -5is perforated as indicated at -19 to allow the hot water and steam topass from the chamber -5% into the sterilizing chamber L to be usedformoistening towels and similar articles used by barbers and also forsterilizing tools and similar object used by for a device of thischaracter.

The perforations l9 extend from the bottom -8- to the top 9- of thesterilizing chamber and therefore the water in the chamber which isheated by the heater -14 is allowed to pass into the chamber :l: as soonas it reaches the level of the upper surface of the bottom 8.

A baflie plate 20 is secured to the partition 7 above the lowermostperforations 19- and extends therefrom into the chamber 4- in spacedrelation to the bottom 8 and is preferably circular in plan but ofconsiderably less diameter than the interior diameter ofthe chamber 4 toform passages for the stem between its marginal edge and walls of theshell.3.

A perforated plate 2l having legs .22- is loosely supported in ahorizontal plane upon the bottom 8- of the chamber 4tso as to underliethe baffle plate 20 in vertically spaced relation thereto. I

This perforated plate 21 is also circular and of substantially the samecrosssectional area as the interior of the chamber 4 except as to aslight clearance around the marginal edges thereof to permit it to beremoved through the top of theshell 3-- when the cover -9is opened.

The water level in the chamber l indicated by the dotted line ismaintained just below the bafiie plate 20 by any suitable means notnecessary to herein illustrate ordescribe while the baffle serves toprevent the direct upward passage of the steam resulting from theheating of the water in the chamber 4- and allows such steam to passupwardly around the marginal edges of the baffle plate and thencethroughthe perforations as Q1 of the plate 2l for moistening orsterilizing anyarticles which may be placed upon said late.

p The bottom 8 of the chamber is provided with heat-insulating material8 to prevent sudden cooling of the hot water which may pass from theheatingchamber into the chamber 41 and also reduces the liability ofcondensation ofthe steam which may be generated as a result of theheating of the water.

The top -9 of the sterilizing chamber &- is hinged at 9 to permit it tobe swung upwardly and laterally for opening the top of the chamber andpermitting articles to be placed through the opening upon the perforatedtray 21 preparatory to moistening orsterilizing after the lid 9 has beenreturned to its closed position.

Operation.

according to the adjustment of the thermostatic bar +16- and when itexceeds that degree the bar l6 will be deflected by the heat impartedthereto to engage and operate the movable switch as for breaking thecircuit through the heater, the degree of temperature being maintainedantomatically by the operation of the thermostatic bar -16 it beingunderstood member 15- is self-closing when released by the withdrawal ofthe thermostatic bar l 6 therefrom as for example when the temperatureof the water in the chamber 5 drops below the predetermined degreementioned.

Under these conditions hot water escapes through the perforations l9-below the baffle plate -20 and into the chamber 4;- across and upon thebottom -8 while the steam rises'around the marginal edges of the baflieplate and escapes upwardly through the perforations in the plate -2l.

It, therefore, follows that any towels tools, or other articles whichmay be placed upon the tray 2lwill be subjected to moisture orsterilization 'or to both moisture and sterilization by the steamescaping upwardly through the perforations in the plate 21 and thatmoistening and sterilizing may be continued indefinitely for the samearticles or repeated with otherarticles as may be'desired.

In other words the maintenance of the hot water and "steam atthe desiredtemperature within the chamber l renders the apparatus available at alltimes for moistening and sterilizing purposes. v

011 the other hand if relatively small quantities'of water for shavingand other purposes are required it is simply necessary to open thefaucet'l8andto discharge the water therefrom into any receptacleprovided forthat purpose.

WVhat I claim is: I l. A combined water heater and sterilizing apparatuscomprising an upright'cylindrical water heating chamber having a waterinlet at its lower end and its upper end closed, a heater supported fromthe closed upper end of the heating chamber above the water inlet and asterilizing chamber embracing a portion of one side of'the heatingchamber above the lower end of the heater, the portion of the heatingchamber embraced by thesterilizing chamber being perforatedto permit thepassage of steam fronrthe heating chamber to the sterilizing chamber.

2. A combined water heaterand sterilizing'apparatus comprising anupright cylindrical water heating chamber having a water inlet at itslower end and its'upper end closed, a heater supported from the closedupper end of the heating chamber above the water inlet, a sterilizingchamber embracing a 7 portion of one side of the heating chamber abovethe lower end of the heater, the

embraced by the sterilizing portion of the heating chamber chamber beingprovided with a seriesro-f perforations arranged one above the other forintercommunication above the lowermost perforations.

between said chambers, and a perforated plate loosely mounted in thesterilizing chamber in a horizontal plane above the water inlet, asterilizing chamber embracing a portion of one side of the heatingchamber above the lower end of the heater, the portion of the heatingchamber embraced by the sterilizing chamber being provided with a seriesof perforations arranged one above the other for intercommunicat-ionbetween said chambers, a perforated plate loosely mounted in thesterilizing chamber in a horizontal plane above the lowermostperforations, and a horizontal baffle plate extending laterally from theperforated side of the heating chamber between the perforated plate andbottom of the sterilizing chamber and of less area than the interior ofthe sterilizing chamber toallow the upward passage of the water andsteam around one edge thereof.

In witness whereof I have hereunto set my hand this 24th day of Nov.,1924.

ALPHONSE MARTIN.
